Anybody have the caffeine count for McDonald’s? I don’t think any chain uses robusta coffee anymore as we’d taste it a mile away, but the coffee to water ratio is a way to play with the price. The caffeine count is higher at Starbucks compared to Tim Hortons, so that would indicated less coffee per volume at Tim Hortons (but they give you more volume per $).

This article indicates the coffee at McDonald’s is quite diluted. Not necessarily a bad thing considering our cold winters, but something to consider before returning to McDonald’s after prices return to normal (or attempting to stay awake with McDonald’s coffee).

An Xtra large at McDonald’s is 660ml, the Tim Hortons version is 678ml and a Venti at Starbucks is 591ml (in the real world, the shape of the cup will also impact how much coffee you get, as the cup is rarely filled to the rim).
